Sustainability Means Inclusivity: Engaging Citizens in Early-Stage Smart City Development

The challenge of how cities can be designed and developed in an inclusive and sustainable direction is monumental. Smart city technologies currently offer the most promising solution for long-term sustainability, but the impact of such solutions will be significantly reduced without long-term, widespread adoption by citizens. In this article, we present the rationale behind an ongoing interdisciplinary research project titled “Sustainability means inclusivity (SuMIn)” that aims to address exactly this problem by using a par-ticipatory design approach. Focusing on a smart city test site in Sweden where sensors are currently being deployed to collect data on, for example, noise, par-ticles, vehicle numbers, and types, the goal is to bring local residents and government representatives into dialogue with technical developers by adopting a “meet-in-the-middle” approach.

Users’ Preferences for Smart Home Automation – Investigating Aspects of Privacy and Trust

Smart home automation provides residents with relief and convenience in everyday life and allows for self-determined aging in place. Yet, market penetration is offset by user concerns related to privacy and trust issues: With increasing system complexity, users may perceive a loss of control and fear technical unreliability. While barriers to acceptance in terms of privacy and trust are well understood when considered separately, they are hardly investigated in conjunction so far. We conducted a quantitative study using Adaptive Choice-Based Conjoint Analysis via an online questionnaire. We explored how aspects of privacy and trust determine the willingness to use smart homes from the perspective of (future) users (n = 137, 18 to 64 years of age), and also with respect to the level of automation and application field. Results show that semi-automated systems are rather preferred than fully automated smart home technology. The perceived reliability of automation is the most important acceptance determinant, followed by the location of data storage. Whereas the awareness to use (e.g., recommendations), the type of data, and application field are less important factors for the overall willingness to use smart homes. Findings inform scientists in the field of human-automation interaction and technical developers of smart home automation for technology innovation adapted to user needs.

Effectiveness of Contact Tracing Using KNN for COVID-19

COVID-19 virus started to outbreak in China in the year January 2020. Contact tracing is an open-minded measure of control that applies to an extensive range of transmissible diseases. It is being used to fight infections like SARS, tuberculosis, smallpox, and many sexually transmitted diseases (STDs). From the moment of the lockdown, there have been a great many talks of applications helping to combat the coronavirus. Technical developers bring a solution to this problem by providing tools that help to contain the coronavirus. This kind of application is helpful, but it lacks in accuracy and privacy concerns. COVID-19 virus, irrespective of causes, solution, treatments, clinical signs, and symptoms is discussed in this paper. The main aim of this paper proposes a contact tracing using k-nearest neighbour, which shows the correct prediction of an affected person of COVID-19 based on the distance and also reduces the transmission of disease. It was tested on the WHO dataset obtained the prediction accuracy of which was carried out on clinical and quarantine data. The evaluation result shows that the contact tracing technique’s accuracy has been improved using the proposed algorithm.

Tele-mentoring using augmented reality technology in healthcare: A systematic review

This systematic review aimed to identify how tele-mentoring systems that incorporate augmented reality (AR) technology are being used in healthcare environments. A total of 12 electronic bibliographic databases were searched using the terms “augmented reality”, “tele-mentoring” and “health”. The PRISMA checklist was used as a guide for reporting. The mixed method appraisal tool was used to assess the quality of the included experiments. The data were then analysed using a concept-centric approach and categorised primarily with regards to system performance and task performance measures. A total of 11 randomised controlled trials and 14 non-randomised designs were included for review. Both mentees and mentors assessed the system and task performance according to 25 categories. The feedback of mentees using AR tele-mentoring systems was generally positive. The majority of experiments revealed that the AR system was an effective tele-mentoring device overall and resulted in the effective performance of a procedure. Benefits included improvements in trainees’ confidence, task completion time and reductions in task errors and shifts in focus. However, the systems had limitations, including heaviness of the equipment, inconvenience, discomfort and distraction of wearing devices, limited battery life, the latency of video and audio signals and limited field of view.&#x0D; &#x0D; Implications for practice or policy:&#x0D; &#x0D; Health practitioners can apply AR technology to receive and follow real-time annotated instructions verbally and visually from remote experts.&#x0D; Technical developers may consider improving AR devices in terms of lighter weight, larger field of view, more ergonomic design, more stable network connection and longer battery life.&#x0D; Further AR-related experiments may need to explore AR tele-mentoring systems’ utility across healthcare environments with larger samples, real patient populations in remote settings, cost-benefit analysis and impacts on short- and long-term patient outcomes.&#x0D;

Augmented reality (AR) app use in the beauty product industry and consumer purchase intention

PurposeDue to the lack of relevant literatures on the application of mobile augmented reality (AR) service in beauty industry, the purpose of this study is to explore the impact of the mobile AR service on consumers' purchase behavior and brand awareness in beauty industry. And this study also wants to identify the different effects of the relationship among flow experience (concentration, playfulness and exploratory behavior), decision comfort and purchase intention moderated by different levels of consumer characteristics (individualism and fashion innovativeness).Design/methodology/approachThis study set up a research model based on SOR model. The study used AR mobile app named “Youcam Makeup” as stimulus to do the questionnaire survey. First, the authors describe the way to use this AR mobile app and make sure each participant experience this app for about 5 min to understand AR well and finally, finished the questionnaire. SPSS and AMOS were used to do data analysis.FindingsThe results of this study showed that first, in the field of fashion and beauty makeup, compared with the ability to control or modify virtual contents – the perception of vividness, reality and aesthetics – are more relevant to consumers. Second, besides the playfulness that AR provides, AR technology can also encourage exploratory behavior in consumers, which will directly affect their intention to purchase. Finally, when using mobile AR technology, consumers with different levels of individualism or fashion innovativeness will gain different perceptions of their purchase intention.Research limitations/implicationsFirst, the study targets millennial female consumers. The future studies can be conducted on consumers of different age groups. Second, the sampling of this study is insufficient; if it had more samples, the results would be more accurate. Finally, AR is integrated into people's lives; therefore, to not be limited to millennial consumers, demographic characteristics need to be applied to future research.Practical implicationsThis study provides a theoretical basis for marketers to formulate marketing strategies. First of all, marketers can use this technology to provide consumers with a more vivid and specific online shopping experience. Second, technical developers can focus on developing the features of AR with the strongest consumer perception based on the results of this study. Finally, this study researched consumer traits that can deepen understanding of both emerging technologies and consumer behavior as compared to research only on mobile AR services. Marketers need to understand the characteristics of consumers when making marketing plans and expand the characteristics of AR technology corresponding to the characteristics of consumers to attract consumers with different attributes.Social implicationsBy using interactive technology, the brand can be closer to consumers and provide help and fun for consumers when they consume online. AR can also lead to future tool reuse behavior, thus establishing long-term relationships with consumers. More than that, AR can be used with the mobile phone, which can be used anytime and anywhere, eliminating space and time constraints. Therefore, the brand can establish cheap and extensive technology as a marketing strategy. Also, it can become one of the most common marketing tools.Originality/valueThis research fills the gap in the literature on mobile AR technology in the beauty industry. Such knowledge will not only facilitate the online development of brands but also help support retailers' development in the beauty industry, providing necessary capabilities for the expansion and application of this new technology. With regard to marketing strategies, the study on consumer characteristic provides the knowledge foundation for marketers to create marketing strategies, which is easier for them to formulate marketing schemes favorable to the brand for varying consumers.

Piece of Cake: Assuring Specific Qualities of Product in Farm Lifecycles with DLT - Can Evidenced-Based Practice be supported by Participatory Action Research Methods?

A strong need for evidence-based practice in the blockchain and distributed ledger technology (DLT) research, development and action domains is currently clarifying. Literature highlights a lack of transparency around the outputs, outcomes and impacts of blockchain projects. As previously cited in this journal for example, the US Agency for International Development studied 43 projects, and found that nearly all did not want to share their results [1]. The Centre for Evidence Based Blockchain recently completed a study of 517 companies to see if their blockchain projects could be defined as evidence-based practice. Over four, years they measured companies using the PCIO framework (what evidence is there of Problem – Comparison – Intervention and Outcomes) of evidence-based practice. The studies concluded that almost half of blockchain companies showed “no explicit evidence of the problem to be solved. Approximately one-third fail[ed] to cite a comparison and intervention analysis, and less than 2% demonstrate[d] evidence of outcomes backed by filtered (critically appraised, peer reviewed) information” (Naqvi & Hussain, p. 8 [2].) This paper presents how qualitative research design and methodologies can help companies and academics achieve evidence-based practice. It presents a case study, in the PCIO framework, of a small-scale agriculture sector project to assure a specific quality. The case study is a conclusion of a project that was run as participatory action research (PAR), involving a consortium including academics, farmer practitioners and a technical DLT platform developer, between 2018 and 2020. The findings show that PAR is an appropriate research method for any democratic collaborative consortia to achieve evidence-based practice through dialogue, discussion, co-development and trusting relationships.

Evidence on User-Led Innovation in Diabetes Technology (The OPEN Project): Protocol for a Mixed Methods Study.

BackgroundDigital innovations in health care have traditionally followed a top-down pathway, with manufacturers leading the design and production of technology-enabled solutions and those living with chronic conditions involved only as passive recipients of the end product. However, user-driven open-source initiatives in health care are becoming increasingly popular. An example is the growing movement of people with diabetes, who create their own “Do-It-Yourself Artificial Pancreas Systems” (DIYAPS).ObjectiveThe overall aim of this study is to establish the empirical evidence base for the clinical effectiveness and quality-of-life benefits of DIYAPS and identify the challenges and possible solutions to enable their wider diffusion.MethodsA research program comprising 5 work packages will examine the outcomes and potential for scaling up DIYAPS solutions. Quantitative and qualitative methodologies will be used to examine clinical and self-reported outcome measures of DIYAPS users. The majority of members of the research team live with type 1 diabetes and are active DIYAPS users, making Outcomes of Patients’ Evidence With Novel, Do-It-Yourself Artificial Pancreas Technology (OPEN) a unique, user-driven research project.ResultsThis project has received funding from the European Commission’s Horizon 2020 Research and Innovation Program, under the Marie Skłodowska-Curie Action Research and Innovation Staff Exchange. Researchers with both academic and nonacademic backgrounds have been recruited to formulate research questions, drive the research process, and disseminate ongoing findings back to the DIYAPS community and other stakeholders.ConclusionsThe OPEN project is unique in that it is a truly patient- and user-led research project, which brings together an international, interdisciplinary, and intersectoral research group, comprising health care professionals, technical developers, biomedical and social scientists, the majority of whom are also living with diabetes. Thus, it directly addresses the core research and user needs of the DIYAPS movement. As a new model of cooperation, it will highlight how researchers in academia, industry, and the patient community can create patient-centric innovation and reduce disease burden together.International Registered Report Identifier (IRRID)PRR1-10.2196/15368

62 Engaging Older Adults in Co-Creating a Virtual Coaching Assistant (CAPTAIN) to Support Independent Living at Home

Abstract Background As population age increases (CSO, 2016), the CAPTAIN project aims to prevent premature or unnecessary transfer to long-term residential care by offering a safe environment where older adults can retain their autonomy, dignity and independence. CAPTAIN (Coach Assistant via Projected and Tangible Interface) will develop a virtual eCoaching assistant to facilitate independence in the home using augmented reality projections, voice and speech recognition, artificial intelligence and a user interface designed by older adults with their peers in mind. Methods Using Design Thinking and participatory research principles, older adults (n=10), caregivers (n=3) and healthcare professionals (HCPs) (n=2) co-create the CAPTAIN system with the research team. Co-creation occurs in cycles. Two co-design cycles use participatory workshops to identify older adults’ needs through discussion of typical older adult ‘personas’, examine how technology can support these needs and translate these outputs into system requirements. Four co-production cycles will evaluate CAPTAIN prototypes (hardware and software) to determine the effectiveness of personalised recommendations, usability and acceptability. The evaluation (involves additional caregivers, HCPs and stakeholder groups) combines observed CAPTAIN use, system-generated data, self-report measures, participatory group workshops and one-to-one interviews. Results Participants found the personas helpful in terms of generating conversation in the co-design sessions. They confidently described older adult needs, suggested where technology could provide useful support, and features they thought CAPTAIN should offer. Requirements across seven thematic areas (health, nutrition, physical and cognitive activity, accessibility, social interaction, education and safety) have now been sent to technical developers. Data from each cycle will continue to inform the development of CAPTAIN until system completion. Conclusion Participant contributions have ensured the continued development of an accessible, easy-to-use assistive technology system that will facilitate independent living and support older adults “…to do the things they want to do, when they want to do them”.

Measuring the quality of e-commerce websites using analytical hierarchy process

This study interviews two experts to assign priority for each criterion. In the end, this study has found that availability is the uttermost aspect to consider. Furthermore, this study also found that OLX.com is the best Customer-to-Customer (C2C) e-commerce in Indonesia in terms of website quality. This research is useful for any e-commerce technical developer to improve his/her website in twofold: 1) criteria priority to improve the quality of C2C e-commerce websites and 2) website quality ranking of C2C e-commerce.

Formal semantics and transformation of BPMN models

Business process modelling notation (BPMN) represents an industrial standard created in order to provide a graphical semi-formal notation that is readily understandable by all business users, from the business analyst to the technical developers, and, finally, to the business people who will manage those processes. However, BPMN models are expressed in a semi-formal modelling language and need a well-defined formal semantics base for their notations. This formalisation enables analysis and verification tasks. Some efforts have been made to transform BPMN models into formal representations including Petri nets, but, to the best of our knowledge, no work has been done for transforming BPMN models into a language that supports a true concurrency semantics, DD-LOTOS. The DD-LOTOS language is defined for the formal specification of distributed real-time systems and has been defined on a semantic model of true concurrency. The main goal of this paper is to propose a formal semantics for a subset of BPMN, defined in terms of DD-LOTOS code. The paper also proposes a model transformation approach to generate DD-LOTOS code from BPMN models. This approach has been implemented using Eclipse Sirius and Eclipse Acceleo. Two well-known case studies are given to illustrate the transformation.

Survey on Domain Specific Languages Implementation Aspects

Domain Specific Languages (DSLs) bridge the gap between the business model and the technical model. DSLs allow the technical developer to write programs with the business domain notations. This leads to higher productivity and better quality than General Purpose Languages (GPLs). One of the main challenges of utilizing DSLs in the current software process is how to reduce the implementation cost and the knowledge required for building and maintaining DSLs. Language workbenches are environments that provide high level tools for implementing different language aspects. The purpose of this paper is to provide a survey on the different aspects of implementing DSLs. The survey includes structure, editor, semantics, and composability language aspects. Furthermore, it overviews the approaches used for each aspect and classify the current workbenches according to these approaches.

Technical Systems Development Risk Factors: The Role of Empowering Leadership in Lowering Developers’ Stress

The success of information systems development (ISD) projects depends on the developers who deliver them. However, developers face many challenges in bringing an ISD project to successful completion. These projects are often large and highly complex, with volatile targets, creating a stressful environment for developers. Although prior literature has considered how technical ISD risk factors, such as project size, complexity, and target volatility, affect team- and project-level outcomes, their effects on developers have received limited attention. This gap in the literature is problematic for two reasons: (1) the interplay between developers and project characteristics are unaccounted for, resulting in an incomplete picture of ISD; and (2) developer stress has been shown to reduce team performance. In this research, we examine the role of empowering leadership in reducing developer stress in ISD. We develop a multilevel model of the effect of empowering leadership on the relationship between technical ISD risk factors and developers’ role perceptions, and explore the consequences for developers’ stress. The model was tested in a field study of 350 developers in 73 ISD teams from a large U.S.-based firm. Results showed that empowering leadership ameliorated the negative effects of project size and target volatility on role ambiguity as well as the negative effects of project size, complexity, and target volatility on role conflict and stress. We also found that empowering leadership reduced role ambiguity, role conflict, and stress directly, and that role ambiguity and role conflict increased stress. Project size, complexity, and target volatility were found to increase empowering leadership behaviors. We conclude that empowering leadership can be an effective means of helping developers cope with technical ISD risk factors and discuss the implications of our findings for research and practice.
